Baron Hill, a Democrat in his fifth term in the House (though not all in a row), is a member of the moderate Blue Dog Coalition. Mr. Hill is accustomed to running against one man – Mike Sodrel, a Republican who has opposed him four times – but Mr. Hill has a different challenge this time: Todd Young, a lawyer and Republican, who has been taking special note of Mr. Hill’s votes for the health care overhaul. Indiana political experts say this race could go either way.
